Great approach! For the past 2 years I keep experimenting with different ways to track day to day productivity. It has helped me tremendously in assessing how I should feel at the end of the day about my work day and the amount of time I put towards work. (I tend to overwork myself significantly). It is of course a lot harder to apply this approach to individual productivity tracking across my teams. But I do now believe, based on self experiments and within smaller teams, that there is generally a lack of visibility of knowledge worker productivity. Especially within larger companies. WFH and hybrid makes this more crucial to have for both management and self assessments on the IC level.
